It's an awesome movie with a great story and strong character. Money minded corporate company do nasty things in a very smarter way which make them profitable but make society sick. Someone stand for it and sacrifices family peace and his own health and try to fight with regulatory authorities as well but ultimately truth win after lots of year. This story will make u cry and make u rethink on many points around the society and your own personality as well. I will give 4 star and will cut one star for not giving history of 1970s in cinematic way and sometime explaining so many things through documentary way.
